BLF6G27S-45,112

Overview

The BLF6G27S-45 is a 45 W LDMOS power transistor designed for base station applications in the 2500 MHz to 2700 MHz frequency range. It operates with a typical supply voltage of 28 V and features an integrated ESD protection circuit. The device is qualified for a maximum drain-source voltage (VDS) of 32 V and offers excellent ruggedness, high efficiency, and thermal stability. It is internally matched for ease of use and compliant with RoHS directives. The component utilizes a ceramic earless flanged package (SOT608B) with two leads.

• Qualified for operation up to 32 V drain-source voltage
• Designed for broadband RF power amplification

Applications

• RF power amplifiers for base stations
• Multi-carrier applications in the 2500 MHz to 2700 MHz range
• WiMAX power amplification

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package configuration. Confirm that the procurement channel provides valid traceability for the component's manufacturing origin. Check for any recent product change notices or end-of-life announcements from Ampleon prior to finalizing orders.

Selection Notes

Select this component for designs requiring 45 W output power within the 2.5 GHz to 2.7 GHz band. Ensure the application circuit supports a 28 V supply and accommodates the SOT608B package dimensions. Verify that the thermal management system can handle the junction-to-case thermal resistance specified in the datasheet under continuous wave conditions.

Part Context

This part belongs to the BLF6G27 series of LDMOS transistors manufactured by Ampleon USA Inc. The 'S' designation indicates the specific earless flanged package variant (SOT608B), distinct from the standard flanged version. These devices are engineered for robust performance in wireless communication infrastructure.

Replacement Considerations

Consult the official Ampleon datasheet for confirmed substitute part numbers. Cross-compatibility should be verified based on pinout, package outline, and electrical specifications rather than assuming direct interchangeability with other RF power transistors.
